Answer:
63
Step-by-step explanation:
90+13x+1+28x+7=180
98+41x=180
41x=82
x=2
Plugging in the value of x, we get:
28x+7=28(2)+7=56+7=63
Answer:
x = 5
Step-by-step explanation:
If x + 5 = 10, then x would have to be 5 because 5 + 5 = 10.
The way you would solve this would be:
x + 5 = 10
subtract 5 from both sides of the equation
x + 5 - 5 = 10 - 5
simplify:
x = 5
