Question

Solve each system algebracally
10x+3y=19
y=2x+5

Answer 1

you know what y is from equation 2

so put the value of y, (2x + 5), into the y for the top equation and solve for x. Tell me where you get stuck (if anywhere)

Answer 2

so

10x + 3(2x + 5) = 19

solve for x

Answer 3

x=1? @JamesWolf

Answer 4

erm lemmi see
10x + 6x + 15 = 19
10x + 6x = 4
x(10+6) = 4
x = 4/16
x = 1/4

Answer 5

you agree?

Answer 6

yes i do i didn't add like terms

Answer 7

where does 15 go?

Answer 8

so

10x + 6x + 15 = 19

take 15 from both sides

10x + 6x + 15 - 15 = 19 - 15

10x + 6x = 4

Answer 9

thanks
