1884 i think the answer is-
If you solve the equation to get the equation y=mx+b then 2x+5y=10 equals to
y=(-2x-10)/5 . If you use a graphing calculator and type that into y= it should graph it for you going through coordinates (-3,4) , (0,-2) , (3,-8) and so forth
2a + 3b, 6ab, And 2b + 3a
<u>Given Equation</u>:-
- 5x+y=17 . . . . . . . . 1
- x+y=3 . . . . . . . . . . 2
<u>To find</u> :
<u>Solution</u> :
<u>Let's start with equation 2</u>:-
x + y = 3
y = 3 - x
Put the value of y in Equation 1
- 5x+y=17
- 5x + (3 - x) = 17
- 5x - x + 3 = 17
- 4x + 3 = 17
- 4x = 17 - 3
- 4x = 14
- x = 14/4
- x = 7/2
- x = <em>3.5</em>
<u>Now Let's find value of y</u><u>:</u>
put the value of x in equation 2:
y = 3 - x
y = 3 - 3.5
y = <em>0.5</em>
Just multiply.
11.76 * 23.5= 276.36
