Question

what is 4x-7+694=

Answer 1

Solve for x:
4 x+687 = 0
Isolate terms with x to the left hand side.
Subtract 687 from both sides:
4 x+(687-687) = -687
Look for two terms that sum to zero.
687-687 = 0:
4 x = -687
Solve for x.
Divide both sides of 4 x = -687 by 4:
(4 x)/(4) = -687/4
Any nonzero number divided by itself is one.
4/4 = 1:
