To sub, solve for 1 variable
solve for y
14-4x=2y
divide by 2
7-2x=y
sub 7-2x for y
(7-2x)+2x=7
7-2x+2x=7
7=7
true
answer is infinite olutions since everybody cancled out

Equation
-------------------------------------------------------------
m + n²
-------------------------------------------------------------
Substitute value of m and n into the equation
-------------------------------------------------------------
When m = 2, n = -2
m + n² = 2 + (-2)²
m + n² = 2 + 4
m + n² = 6
-------------------------------------------------------------
Answer : 6
-------------------------------------------------------------
1) Is A- x < -3, or x> 5 (d=cant put the line under the second one)
2) C- 25<*with line under* x >with line under*30 Because its between 25, so must be more, and 30, so has to be less than 30
3)?
4)?
15.
Dividing by a fraction is the same as multiplying by it's reciprocal. <span />
