80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
The answer is 450. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
46 + 29 = 75

80 = 3y + 2y + 4 + 1 75 = 5y 15 = y y = 15

80 = 3y + 2y + 4 + 1 80 = 5y + 5 80 - 5 = 5y + 5 - 5 75 = 5y 75 / 5 = 5y / 5 15 = y
3y+2y+4+1=80 5y+5=80 5y=80-5 5y=75 y=15
Presumably you want to know the value of y. 3y+2y+4+1 = 80 5y+5 = 80 5y = 80-5 5y = 75 y = 15
no it equals 228
90 minus 75 =15 therefore 15 + 75 = 90
75 + 16 + 25 = 116
23 + 56 - 4 = 75
The answer is 450. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
