Step-by-step explanation:
- 12 + x ≥ 3 (x - 6)
- or, 12 + x ≥ 3x - 18
- or, 12 + 18 ≥ 3x - x
- or, 30 ≥ 2x
- or, 30/2 ≥ x
- or, 15 ≥ x
- or, x ≤ 15

Answer:
x = -1
y = 5
Step-by-step explanation:
x+y=4
3x+7y=32
<em><u>To solve a pair of equations using substitution, first solve one of the equations for one of the variables. Then substitute the result for that variable in the other equation.</u></em>
x+y=4,3x+7y=32
<em><u>Choose one of the equations and solve it for x by isolating x on the left hand side of the equal sign.</u></em>
x+y=4
<em><u>Subtract y from both sides of the equation</u></em>.
x=−y+4
<em><u>Substitute −y+4 for x in the other equation, 3x+7y=32.</u></em>
3(−y+4)+7y=32
<em><u>Multiply 3 times −y+4.</u></em>
−3y+12+7y=32
<em><u>Add −3y to 7y.</u></em>
4y+12=32
<em><u>Subtract 12 from both sides of the equation</u></em>.
4y=20
<em><u>Divide both sides by 4</u></em>.
y=5
<em><u>Substitute 5 for y in x=−y+4. Because the resulting equation contains only one variable, you can solve for x directly.</u></em>
x=−5+4
<em><u>Add 4 to −5.</u></em>
x=−1
