-3x+4y=7 y=3x-5 I NEED HELP PL Z HELP ME

andrew-mc [135]

$- 3x + 4y = 7 \\ y = 3x - 5$

[Substitute the given value of y into the first equation]

$- 3x + 4 \times (3x - 5) = 7$

[Distribute 4 through the parentheses]

$- 3x + 12x - 20 = 7$

[Collect like terms]

$9x - 20 = 7$

[Move the constant to the right-hand side and change its sign]

$9x = 7 + 20$

[Add the numbers]

$9x = 27$

[Divide both sides of the equation by 9]

$x = 3$

[Substitute the given value of x into the second equation]

$y = 3 \times 3 - 5$

[Multiply the numbers]

$y = 9 - 5$

[Subtract the numbers]

$y = 4$

[The possible solution of the system is the ordered pair (x,y)]

$(x,y)=(3,4)$

1. What is the measure of angle x? 2. What is the measure of angle x?

MrRa [10]

1. These angles are complementary, which means that they add up to 90 degrees.

x + 73 = 90

x = 17 degrees

2. These angles are supplementary, which means that they add up to 180 degrees.

x + 118 = 180

x = 62 degrees

Hope this helps!! :)

Y=6/13X is a proportional relationship

Ivan

Answer:

x in (-oo:+oo)

Y = (6/13)*x // - (6/13)*x

Y-((6/13)*x) = 0

Y+(-6/13)*x = 0

Y-6/13*x = 0 // - Y

-6/13*x = -Y // : -6/13

x = -Y/(-6/13)

x = 13/6*Y

3(1)+2(_)=6 plz help on filling in the blank

TEA [102]

Answer:

x = 3/2

Step-by-step explanation:

Let's solve your equation step-by-step.

(3)(1)+2x=6

Step 1: Simplify both sides of the equation.

(3)(1)+2x=6

3+2x=6

2x+3=6

Step 2: Subtract 3 from both sides.

2x+3−3=6−3

2x=3

Step 3: Divide both sides by 2.

2x/2 3/2

x = 3/2

Hope this helps :)
