Solve each equation. See Sections 2.3 and 5.5 $$ -8 x+7=4 $$
Added by Dawn C.
Step 1
To do this, we need to get rid of the constant term on the same side as x. We can do this by subtracting 7 from both sides of the equation: $$-8x + 7 - 7 = 4 - 7$$ Simplifying the left side gives: $$-8x = -3$$ Now we can isolate x by dividing both sides by -8: Show more…
