New Learning Composite Mathematics SK Gupta Anubhuti Gangal Class 8 Linear Equations Practice 7A Solution
Solve:
(1) 8x + 14 = 5x + 44
(2) 5, + 7 = 10m – 3
(3) 8y – 14 = 6 – 2y
(4) 6p – 21 = p + 4
(5) 2(x – 1) = 12
(6) 7 + 3(t + 5) = 31\
(7) 15 + 3(4x – 30) = 33
(8) 5(x+2) – 9 (x – 2) = 0
(9) 3x + 5 = 0.5x – 7
(10) 0.1 (t – 3) = 0.15(t – 4)
SOLUTION:
(11) 2(x – 2) + 5 = 4(x – 6) + 3
(12) 2m(m – 4) – 8 = m(2m – 12)
(13) 3a + 2(a – 9) = 6 – (2a – 3)
(14) 8x – 2(2 + 3x) = 2(1 – 2x) – 3(x – 1)
SOLUTION:
(15) x/2 + x/3 + x/6 = 18
(16) 2x/3 + x/4 + x/2 = 34
(17) p + 1/2 – 2(p – 1)/3 = 0
(18) 6 – 3(n – 7)/4 = 1/2n
(19) 10 – 5(1+x)/3 + 3x+1/5 = 0
(20) 2b + 1/5 – b-1/3 = 1
(21) 5(1 -z)/3 – 3z-1/5 = 1/6
(22) x+5/15 – x-5/10 = 1 + 2x/15
SOLUTION:
(23) 3x-4/6 – 2x+3/8 = 2x-7/24
(24) (x+0.5) + 1/2(3x – 1/3) = 1/3(x+1)
(25) 9x-5/7 = 6x+2/5
(26) 7x-10/5 = 8x-5/7
SOLUTION:
(27) 2x-7/x+4 = 3/4
(28) 3m+4/2-6, = -2/5
(29) 2n-3/2n-1 = 3n-1/3n+1
SOLUTION:
in 6th one answer is 7.66
