Answer:

(-2, 5)

Step-by-step explanation:

we subtract 6x+3y=3 by 2x+3y=11 to get 4x=-8.

we divide both sides by 4 to get x. x=-2

We subsitute -2 for the second equation to get:

2(-2)+3y=11

=-4+3y=11

=3y=15

y=5

lisabon 2012 [21]

I'm assuming you need to evaluate/simplify the equation, so you need to isolate/get x by itself in the equation:

2(3x + 1) = 11        Divide by 2 on both sides

3x + 1 = \frac{11}{2}        [11/2 or 5.5] Subtract by 1 on both sides

3x=\frac{11}{2}-\frac{2}{2}            [make the denominator the same to combine fractions]

3x = \frac{9}{2}        Divide by 3 on both sides

x = \frac{9}{6}=\frac{3}{2}

Simplify expressions <br> 2=3/4x-7
Gnesinka [82]

Answer: x = 12

Step-by-step explanation:

2=\frac{3}{4}x-7

Add 7 on both sides to get rid of the 7 and isolate x.

+7+2=\frac{3}{4}x-7+7

9=\frac{3}{4}x

Now multiply both sides by \frac{4}{3} to eliminate it and isolate x.

(\frac{4}{3})(9)=(\frac{3}{4}x) (\frac{4}{3})

12=x

Proof;

2=\frac{3}{4}x-7\\2=\frac{3}{4}(12)-7\\2=9-7\\2=2
