1) Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation.
(3 • (x - 1) - 2x) - 9 = 0
Solve x-12 = 0
Add 12 to both sides of the equation
x = 12
2)Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
(5d + 4 • (3 - d)) - 36 = 0
Solving a Single Variable Equation
d - 24 = 0
Add 24 to both sides of the equation
d = 24
3) ((98 - 9y) + 10 • (y + 3)) - 213 = 0
y - 85 = 0
Solve : y-85 = 0
Add 85 to both sides of the equation :
y = 85
4)(-67c + 4 • (17c + 1)) - 768 = 0
c - 764 = 0
Solve : c-764 = 0
Add 764 to both sides of the equation :
c = 764
Hi Barrett,
1. 3(x − 1) − 2x = 9
3(12 - 1) - 2(12) = 9
3 x 11 - 24 = 9
33 - 24 = 9
x = 12
2. 5d + 4(3 − d) = 36
5d+4(3−d)=36
5d+(4)(3)+(4)(−d)=36
5d+12+−4d=36
(5d+−4d)+(12)=36
d+12=36
d+12=36
d+12−12=36−12
d = 24
3. 98 − 9y + 10(3 + y) = 213
98 - 9(85) + 10(3 + 85) = 213
98 - 765 + 880 = 213
-667 + 880 = 213
y = 85
4. −58 + 2(h − 29) − h = 41
-58 + 2(157 - 29) - 157 = 41
-58 + 256 - 157 = 41
198 - 157 = 41
h = 157
5. −67c + 4(17c + 1) = 768
−67c+4(17c+1)=768
−67c+(4)(17c)+(4)(1)=768
−67c+68c+4=768
(−67c+68c)+(4)=768
c+4=768
c+4=768
c+4−4=768−4
c = 764
Hope This Helps!
