Remember you can do anything to an equation as long as you do it to both sides

-3x+1+10x=x+4

add like terms
7x+1=x+4
minus x both sides
6x+1=4
minus 1 both sides
6x=3
divide both sides by 6
x=1/2
x=0.5

On Eduardo's workbench are the following
Maurinko [17]

Answer: 2/5

Step-by-step explanation:

Number of cans of red paint = 3

Number of cans of blue paint = 5

Number of cans of green paint = 8

Number of cans of yellow paint = 4

Total number of cans of paint = 20

The probability that Eduardo will

choose a can of red paint or a can of blue will be:

= P(red) + P(blue)

= 3/20 + 5/20

= 8/20

= 2/5

The probability is 2/5.

Please please help me!!!!!
Maru [420]

Answer:

(12, 487)

Step-by-step explanation:

y = 3.7x + 442 ----› Eqn. 1

y = 14.4x + 312 ----› Eqn. 2

Substitute y = (3.7x + 442) into eqn. 2.

y = 14.4x + 312 ----› Eqn. 2

3.7x + 442 = 14.4x + 312

Collect like terms

3.7x - 14.4x = -442 + 312

-10.7x = -130

Divide both sides by -10.7

x = 12.1495327

Substitute x = 12.1495327 into eqn. 1.

y = 3.7x + 442 ----› Eqn. 1

y = 3.7(12.1495327) + 442

y = 486.953271

The solution to the system is rounded to the nearest integer:
