Answer:

x = 2, y = -1.

Step-by-step explanation:

2x + y = 3

x  -   y  = 3

Adding the 2 equations eliminates y:

3x = 6

x = 2.

Substitute for x in the first equation:

2(2) + y = 3

y = 3 - 4

y = -1.

Check the results by substitution in equation 2:

2 - (-1)

= 2 + 1 = 3 .

Checks OK.

Find the equation of the straight line which is parallel to 2x + 3y = 11 and such that the sum of the intercepts on axes is 15.
Burka [1]

Answer: 2x+3y=18



Step-by-step explanation: Any line parallel to 2x+3y+11=0 is the form 2x+3y =k this can also be written as x/(k/2)+y/k/3 =1  this is the line whose sum of the intercepts is 15, then k/2 +k/3 = 15 after solving we get that indeedk= 18.

Can someone help me solve for X :( I’m stressing out please HELP !
Leni [432]

Answer:

7

Step-by-step explanation:

28 ÷ 16 = 1.75

1.75 × 4 = 7

The way I did it is by finding out how much bigger 28 is than 16 by dividing and then I multiplied the answer (1.75) by 4 to get the bigger answer. The problem is showing you that the triangles are the same just different sizes.
