What is the solution to the linear equation?
d – 10 – 2d + 7 = 8 + d – 10 – 3d
d = –5
d = –1
d = 1
d = 5

d – 10 – 2d + 7 = 8 + d – 10 – 3d; -d - 3 = -2d - 2; -d + 2d = -2 + 3; d = 1

d – 10 – 2d + 7 = 8 + d – 10 – 3d;

-d - 3 = -2d - 2;

-d + 2d = -2 + 3;

d = 1

-d - 3 = -2d - 2;

-d + 2d = -2 + 3;

d = 1

Solve the equation.
–3x + 1 + 10x = x + 4
User: Solve the equation.
–9x + 1 = –x + 17
x = –8
x = –2
x = 2
x = 8

–3x + 1 + 10x = x + 4;

7x + 1 = x + 4;

7x - x = 4 - 1;

6x = 3;

x = 3/6;

x = 1/2

7x + 1 = x + 4;

7x - x = 4 - 1;

6x = 3;

x = 3/6;

x = 1/2

–9x + 1 = –x + 17;

-9x + x = 17 - 1;

-8x = 16;

x = 16/-8;

x = -2

-9x + x = 17 - 1;

-8x = 16;

x = 16/-8;

x = -2
