Question

How do you solve these two? Show work and answer

Answer 1

6) -7+8x= -5+7x first add 7 both sides

8x=-2+7x the subtract 7x both sides

x=2

8) 3k+5=k-7 first subtract k on both sides

2k+5=-7 then subtract 5 both sides

2k=-12 the final step divide

k= -6

Answer 2

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

−7+8x=−5+7x

Step 1: Simplify both sides of the equation.

8x−7=7x−5

Step 2: Subtract 7x from both sides.

8x−7−7x=7x−5−7x

x−7=−5

Step 3: Add 7 to both sides.

x−7+7=−5+7

x=2
