<span>yes it is a true equation.. you can solve it to find q ...
-5(3-9) 4 = 5q - 11
</span><span>−5 *−6 * 4= 5q−11</span><span>120 = 5q−11
120 + 11 = 5q
131 = 5q
q = 131/5
in decimals q = </span><span> 26.2 ..

Hope it helps!!!!

Answer:
3x - y = 1
Step-by-step explanation:
This will be the same equation written in a different way'
The original equation is:
y = 3x - 1
0 = 3x - y - 1
3x - y = 1.
Answer:
-43.75
Step-by-step explanation:
-35.25-8.5
your already at -35.25 and if you go deeper 8.5 you subtract it
Answer:
-4/3
Step-by-step explanation:
Answer:
Is one of them supposed to by x?
Step-by-step explanation:
6x- y = 11
-4x + 5y = 8
With a system of equations, you need to solve for one variable first and the substitute to find the other variables. y is easier to solve for.
6x - y =11 Subtract 6x to both sides.
-y = -6x +11 Multiply by -1 on both sides
y = 6x - 11
We now subsitute y with 6x - 11 in the other equation.
-4x + 5y = 8
-4x + 5(6x-11) = 8
-4x +30x -55 =8
26x = 63
x = 63/26
and now we subsitute this to solve for actual y.
y= 6x -11
y= 6*(63/26)-11
