What is the solution to 3x -2y =1 and 4y = 7 + 3x
Delvig [45]

Given.

3x-2y=1 (1)

4y=7+3x (2)

Re-arrange equation (2)

(4y=7+3x)-4y

0=-4y+3x+7

(0=-4y+3x+7)-7

-7=-4y+3x

Multiply equation (2) by -1

-1(3x-4y=-7)

-3x+4y=7(3)

Combine like terms and solve.

3x-3x-2y+4y=1+7

2y=8

Divide by (2y) and solve for (y).

\frac{2y}{2}=\frac{8}{2}

y=4

Substitute (y) for equation (1).

3x-2y=1

3x-2(4)=1

3x-8=1

Add (8) to both sides.

(3x-8)+8=(1)+8

3x=9

Divide by (3).

\frac{3x}{3}=\frac{9}{3}

x=3

Check your work.

3x-2y=1

3(3)-2(4)=1

9-8=1

1=1

4y=7+3x

4(4)=7+3(3)

16=7+9

16=16

Your answers is x=3 and y=4
