I = {2.666666667, 1.166666667
<span>3(5x + 4) - 20 - 13x = -4
first use the distributive property with </span><span>3(5x + 4)
15x+12-20-13x=-4
combine like terms
2x-8=-4
add 8 to both sides
2x=4
divide both sides by 2
x=2</span>

Step-by-step explanation:
Answer:
2x + 5y = -4
Step-by-step explanation:
The standard form for linear equations in two variables is Ax+By=C. For example, 2x+3y=5 is a linear equation in standard form. When an equation is given in this form, it's pretty easy to find both intercepts (x and y). This form is also very useful when solving systems of two linear equations.
Let one piece be x inches long then the other piece is 180-x inches long.
3x > 4 (180-x)
3x > 720 - 4x
7x > 720
x > 103 6/7 ins
the 2 pieces could be 107 inches and 180-107 = 73 inches
