Question

Solve the following equations. Check your work.

1. 5m + 4 = 7m + 6


2. -5x + 3 = 2x - 1

Answer 1

m= -1

x= 4/7

Explanation:

Answer 2

1)m= -1

2)x=4/7

Explanation:

1)Subtract 7m from both sides. 2)Step 1: Subtract 2x from both sides.−5x+3−2x=2x−1−2x -5x+3-2x=2x-1-2x

-7x+3=-1

Step 2: Subtract 3 from both sides

−7x+3=−1 -7x+3-3=-1-3

Step 2: Subtract 3 from both sides. -7x=-4

Step 3:Divide both sides by -7

−7x+3−3=−1−3 -7x/7=-4/7

−7x=−4

Step 3: Divide both sides by -7. x=4/7

5m+4−7m=7m+6−7m

−2m+4=6

Step 2: Subtract 4 from both sides.

−2m+4−4=6−4

−2m=2

Step 3: Divide both sides by -2.

−2m
