Answer:

A) Y=x+2

B) 4x+3y= -36

we rearrange A) as -x + Y =2 and multiply it by 4

A) -4x + 4y = 8 then we add B)

B) 4x +3y = -36

7y = -28

y = -4

A) -4 = x +2

x = -6

Answer:

(-6, -4)

Step-by-step explanation:

Use substitution.

Since y is already isolated, substitute it into the y of: 4x+3y=-36.

You should get: 4x+3(x+2)=-36

Simplify this and you'll get:

4x+3x+6=-36

Add both of the variables:

7x+6=-36

Add -6 to both sides, (because there is a -36 on one side, and a 6 on the other, you have to add a negative to eliminate the 6 whilst adding to the -36)

7x=-42

Divide both sides by 7:

x=-6


Now substitute this into y=x+2

y=-6+2

y=-4

Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

Let's first write down the equation we are going to solve.

( 1 / 3 )h - 4 [ ( 2 / 3 )h - 3 ] = ( 2 / 3 )h - 6

To begin with, we will expand the brackets => [ ]

( 1 / 3 )h - ( 8 / 3 )h + 12 = ( 2 / 3 )h - 6

Next we will collect like terms by placing all the individual numbers on the right-side of the equation and the terms with ( h ) on the left-hand side of the equation so that we can begin making ( h ) the subject.

( 1 / 3 )h - ( 8 / 3 )h - ( 2 / 3 )h = - 6 - 12

Then we will simplify both the left-hand side and right-hand side of the equation to solve it for ( h ).

( - 9 / 3 )h = - 18

- 3h = - 18

h = - 18 / - 3

h = 18 / 3

h = 6

FINAL ANSWER:

Therefore, the answer is:

h = 6

Hope this helps! :)

Given that,

Length of 4 pieces of wood are 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.

To find,

The length of the strip of wood.

Solution,

Mark glues together four pieces of wood to make one long strip.

Long strip = The sum of 16.75 inches, 9 inches, 24.25 inches, and 12.5 inches.

L = 16.75 + 9 + 24.25 + 12.5

= 62.5 inches

Hence, the strip of wood is 62.5 inches long.
