Answer:
4=x
Step-by-step explanation:
4+(4+4)=12
y=8
x=4
first since we have the variable "x" on both sides of the equation, we can subtract the lower number to make sure x is only on one side (subtract 10x from both sides)
20x + 4 = 10x + 100
10x + 4 =100
now we can subtract 4 from both sides
10x = 96
now we can divide both sides by 10 to isolate x
x = 9.6

Answer:
60
Step-by-step explanation:
∑[i=1,5] 4i = 4·1 + 4·2 + 4·3 + 4·4 + 4·5
