4(x+5)-10 = 54
4x + 20 - 10 = 54
4x + 10 = 54
4x = 54 - 10
4x = 44
x = 44/4
x = 11
Answer:
x=11
Step-by-step explanation:
Using PEMDAS, you start by distributing the 4 among (x+5)
4*x=4x, 4*5=20
so you are left with 4x+20-10=54
simplify like terms (20-10=10)
this leaves you will 4x+10=54
Now you need to solve for x by moving everything else to the other side of the equal sign
to get rid of +10 on the left side, you must subtract 10 on both sides
4x=44
Now to get rid of the four, divide both sides by 4
x=11
