Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
4x+10 = 2x+26
4x-2x+10=2x-2x+26 [Subtract 2x from both sides]
2x+10=26
2x + 10 - 10 = 26 - 10 [Subtract 10 from both sides]
2x = 1
2x/2 = 16/2 [Divide both sides by 2]
x = 8
CHECK:
Does 4x+10 = 2x+26 when x is 8?
4(8)+10 = 2*(8)+26 ?
32+10 = 16+26 ?
42 = 42 <u>YES</u>
Using the ratio 4/2 = 2
and 8/4 = 2
so they are similar because 4/2 equals 8/4
