a set of equations is given below:

equation e: a = 5b + 1
equation f: a = 3b + 4

which statement describes a step that can be used to find the solution to the set of equations? (1 point)

equation f can be written as 5b + 1 = 3b + 4.

equation f can be written as b + 1 = 3b + 4.

equation f can be written as a = 3(a – 1) + 4.

equation f can be written as a = 5(a – 4) + 1.

step-by-step explanation:

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
