Step 1. 5x-4(-3x+5)=-3
step 2. distribute 5x+12x-20=-3
step 3. combine like terms 17x-20=-3
step 4. add 20 17x=17
step 5. divide 17 x=1
step 6. fill x in first equation y=-3(1)+5
step 7. combine y=2
x=1 y=2

step 1. fill in for y -3x-3(-5x-17)=3
step 2. distribute -3x+15x+ 51=3
step 3. combine 12x+51=3
step 4. minus 51 12x= 48
step 5. divide by 12 x= 4
step 6. fill in x to find y y=-5(4)-17
step 7. combine y=-20-17
y=-37 x=4

Can some one help me plz with step by step<br> x^2 + x - 42
Alexeev081 [22]

Answer:

x = 6 or x = -7

Step-by-step explanation:

Solve for x over the real numbers:

x^2 + x - 42 = 0

The left hand side factors into a product with two terms:

(x - 6) (x + 7) = 0

Split into two equations:

x - 6 = 0 or x + 7 = 0

Add 6 to both sides:

x = 6 or x + 7 = 0

Subtract 7 from both sides:

Answer: x = 6 or x = -7

Write the equation for:
xenn [34]

Answer:

\frac{1}{2} x +x = 2 (x-4)

Step-by-step explanation:

Suppose number is x

Following equation can be written from question statement

\frac{1}{2} x +x = 2 (x-4)

Simplifying it further

\frac{3}{2} x = 2x-8

\frac{3}{2} x -2x=-8

\frac{3x-4x}{2}= -8

-x= -16\\x=16

On a coordinate grid, AB has an end point B at (24, 16). The midpoint of AB is P(4, -3). What is the y-coordinate of Point A?
inysia [295]

The y-coordinate of point A is -22

Step-by-step explanation:

Given

B = (24,16)

P = (4,-3)

The formula for mid-point of AB will be given by:

P = (\frac{x_A+x_B}{2} , \frac{y_A+y_B}{2})

As we already know the y-coordinate of midpoint

We can put the formula's y coordinate equal to the given value

\frac{y_A+y_B}{2} = -3\\\frac{y_A + 16}{2 } = -3\\y_A+16 = -3 * 2\\y_A +16 = -6\\y_A = -6-16\\y_A = -22

Hence,

The y-coordinate of point A is -22
