Answer:
Let's solve your equation step-by-step.
4(u+1)=12
Step 1: Simplify both sides of the equation.
(4)(u)+(4)(1)=12(Distribute)
4u+4=12
Step 2: Subtract 4 from both sides.
4u+4−4=12−4
4u=8
Step 3: Divide both sides by 4.
4u/4=8/4
u=2
3
Step-by-step explanation:
first you multiply the 4 by the u and by the 1 and then you get 4u+4=12 then you subtract the 4 by the both sides and you get 4u=8 and the you divide 4 in the both sides and you get u=2 and then you add the 2+1
