Expand the expression 7 (9x-2)

Masteriza [31]

If you would like to expand the expression 7 * (9 * x - 2), you can do this using the following steps:

7 * (9 * x - 2) = 7 * 9 * x - 7 * 2 = 63 * x - 14

The correct result would be 63 * x - 14.

1/2x+1/4y=6. 1/5x+1/3y=1

Ierofanga [76]

$\frac{1}{2}x+\frac{1}{4}y=6 \ \ \ |\times 2 \\
\frac{1}{5}x+\frac{1}{3}y=1 \ \ \ |\times (-5) \\ \\
x+\frac{1}{2}y=12 \\
\underline{-x-\frac{5}{3}y=-5} \\
\frac{1}{2}y-\frac{5}{3}y=12-5 \\
\frac{3}{6}y-\frac{10}{6}y=7 \\
-\frac{7}{6}y=7 \\
y=7 \times (-\frac{6}{7}) \\
y=-6 \\ \\
x+\frac{1}{2}y=12 \\
x+\frac{1}{2} \times (-6)=12 \\
x-3=12 \\
x=12+3 \\
x=15 \\ \\
\boxed{(x,y)=(15,-6)}$
