Nvm i have a new question i need to know if the answer is correct
insens350 [35]

<em>multiply the numbers.</em>

4 x 6 + y = 20

<em>move constant (24) to the right side and change its sign.</em>

24 + y = 20

<em>calculate the difference and you get the answer.</em>

y = 20 - 24

y = -4

So the value of y is -4.

Classify the system of equations. 2x + y - 3 = 0 x + y - 1 = 0
natta225 [31]
Solve the following system:
{-3 + 2 x + y = 0 | (equation 1)
{-1 + x + y = 0 | (equation 2)

Express the system in standard form:
{2 x + y = 3 | (equation 1)
{x + y = 1 | (equation 2)

Subtract 1/2 × (equation 1) from equation 2:
{2 x + y = 3 | (equation 1)
{0 x+y/2 = (-1)/2 | (equation 2)

Multiply equation 2 by 2:
{2 x + y = 3 | (equation 1)
{0 x+y = -1 | (equation 2)

Subtract equation 2 from equation 1:
{2 x+0 y = 4 | (equation 1)
{0 x+y = -1 | (equation 2)

Divide equation 1 by 2:
{x+0 y = 2 | (equation 1)
{0 x+y = -1 | (equation 2)

Collect results:
Answer: {x =2 , y = -1
