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
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
