No.117 Solve an Equation for x
POINT
Move terms as you would when solving an equation, and transform the equation so that the final form is \(x=\cdots\).
Solve each equation for x.
Example
\(x+5=2y\)
\(9x=-3y\)
\(5x-3y=2\)
① \(x=2y-5\)
② \(x=-\frac13y\)
③ \(x=\frac{3y+2}{5}\)
② \(x=-\frac13y\)
③ \(x=\frac{3y+2}{5}\)
Try it yourself.
Solve each equation for x.
PRACTICE 01
\(x-4=3y\)
\(x=3y+4\)
PRACTICE 02
\(6x=5y\)
\(x=\frac56y\)
PRACTICE 03
\(4x+y=7\)
\(x=\frac{7-y}{4}\)
PRACTICE 04
\(3y-2x=8\)
\(x=\frac32y-4\)
PRACTICE 05
\(7x-4y=-3\)
\(x=\frac{4y-3}{7}\)
PRACTICE 06
\(2x+5y=1\)
\(x=\frac{1-5y}{2}\)
