Take MCQ Maths Test1.
Draw the graph of y = 5 x
| x | -3 | -1 | 0 | 2 | 3 |
| y | -15 | -5 | 0 | 10 | 15 |
2.
Solve 2x + 5 = 9
3.
Solve the equation: 3x = 51
4.
Solve the equation: x − 7 = 6
5.
The sum of 4 times a number and 18 is 28.
1.
The given equation y = 5 x means that for any value of x , y takes five
times of x value.
Plot the point (−3,−15) (−1,−5) (0,0) (2,10) (3,15)
| x | y=5x+1 |
| −3 −1 0 2 3 |
5 × (−3) = −15 5 × (−1) = −5 5 × (0) = 0 5 × (2) = 10 5 × (3) = 15 |

2.
2x = 9 − 5
2x = 4
x = \(\frac { 4 }{ 2 } \)
x = 2
3.
3x = 51 (Given)
3 x x = 51
\(\frac { 3\times x }{ 3 } =\frac { 51 }{ 3 } (\div 3\quad on\quad both\quad sides)\)
x = 17
likewise, doing division by 3 on both sides is the same as changing the number 3 on the LHS to it's reciprocal \(\frac { 1 }{ 3 } \) and multiplying it on the RHS and vice-versa.
4.
x – 7 = 6
x – 7 + 7 = 6 + 7
x = 13
5.
Let the number be x.
4 times the number is 4x.
Adding 18 now, we get 18 + 4x.
The result now should be 28.
Thus, the equation has to be 18 + 4x = 28.
