Solve the system of linear equations in two variables by elimination or substitution.

taurus [48]

Answer:

( $\frac{1}{2}$ , 0 )

Step-by-step explanation:

Given the 2 equations

4x + 3y = 2 → (1)

2x - 3y = 1 → (2)

Adding (1) and (2) term by term will eliminate the y- term, that is

6x = 3 ( divide both sides by 6 )

x = $\frac{3}{6}$ = $\frac{1}{2}$

Substitute x = $\frac{1}{2}$ into either of the 2 equations and evaluate for y

Substituting into (1)

4( $\frac{1}{2}$ ) + 3y = 2

2 + 3y = 2 ( subtract 2 from both sides )

3y = 0 ⇒ y = 0

Solution is ( $\frac{1}{2}$ , 0 )

Solve for rv=r+at, for r

mafiozo [28]

$v=r+at$

Since we need to solve for r we have to leave that variable alone in one side of the equation. We notice that at is adding in the right side, then it goes to the left side substracting, that is:

$v-at=r$

Therefore:

$r=v-at$

in the last part we only switch the sides of the equation.
