Ineed with the following: -3y+10=14 r-11 / 3 = -- 7

3y+10=14r-11 / 3 = -- 7  ( i hope this is a typo and only -7 not --7, otherwise this is wrong, i ll'add it to the end.solve the following system: {10 - 3 y = 14 | (equation 1){r - 11/3 = -7 | (equation 2)express the system in standard form: {-(3 y)+0 r = 4 | (equation 1){0 y+r = -10/3 | (equation 2)multiply equation 2 by 3: {-(3 y)+0 r = 4 | (equation 1){0 y+3 r = -10 | (equation 2)divide equation 2 by 3: {-(3 y)+0 r = 4 | (equation 1){0 y+r = (-10)/3 | (equation 2)divide equation 1 by -3: {y+0 r = (-4)/3 | (equation 1){0 y+r = -10/3 | (equation 2)collect results: answer: {y = -4/3                {r = -10/3answer for --7solve the following system: {10 - 3 y = 14 | (equation 1){r - 11/3 = 7 | (equation 2)express the system in standard form: {-(3 y)+0 r = 4 | (equation 1){0 y+r = 32/3 | (equation 2)multiply equation 2 by 3: {-(3 y)+0 r = 4 | (equation 1){0 y+3 r = 32 | (equation 2)divide equation 2 by 3: {-(3 y)+0 r = 4 | (equation 1){0 y+r = 32/3 | (equation 2)divide equation 1 by -3: {y+0 r = (-4)/3 | (equation 1){0 y+r = 32/3 | (equation 2)collect results: answer:   {y = -4/3                      {r = 32/3

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

The answer maybbe c
