Y=−4x−5
y=3x−2
is (3,7) a solution of the system?

Step-by-step explanation:

Put (3, 7) → x = 3 and y = 7  to the each equation and check the equality:

y = -4x - 5

R = -4(3) - 5 = -12 - 5 = -17

L = 7

L ≠ R

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10
